WASHINGTON Nike Air Max 90 White Leather Shoes , Feb. 2 (Xinhua) -- An international team has shown that quantum computers can analyze relationships within large sets of data faster than classical computers, for a wider array of data types than previously expected.


The study, published on Friday in American journal Physical Review Letters, proposed a "quantum linear system algorithm" that could conduct quantum computation with application in artificial intelligence (AI) and crunch numbers on problems such as commodities pricing, social networks and chemical structures.


The linear system algorithm Nike Air Max 90 Black Leather Shoes , first proposed in 2009, works on a large matrix of data and has kick-started research into quantum forms of machine learning, or artificial intelligence.


"There is a lot of computation involved in analyzing the matrix. When it gets beyond say 10,000 by 10,000 entries Nike Air Max 90 Leather Shoes , it becomes hard for classical computers," explained Zhao Zhikuan, the paper's corresponding author from Singapore University of Technology and Design.


Zhao also said the previous quantum algorithm of this kind can be applied to a very specific type of problem. This is because the number of computational steps goes up rapidly with the number of elements in the matrix: every doubling of the matrix size increases the length of the calculation eight-fold.


Zhao and his colleague in Singapore, Switzerland and the United Kingdom, present a new algorithm that is faster than both the classical and the previous quantum versions.


It relies on a technique known as quantum singular value estimation and can cope with data not limited to "sparse" ones as required by the previous versions.


There are limited relationships among the elements in sparse data Nike Air Max 90 Black Shoes , but it is often not true of real-world data, Zhao said.


For example, a trader might be trying to predict the future price of goods. The matrix may capture historical data about price movements over time and data about features that could be influencing these prices, such as exchange rates.


Then the algorithm calculates how strongly each feature is correlated with another by "inverting" the matrix. This information can then be used to extrapolate into the future.


But to show a real quantum advantage over the classical algorithms will need bigger quantum computers.


Zhao estimates that it still need additional three to five years when they can actually use the hardware to do meaningful quantum computation with application in artificial intelligence.




JIUQUAN, Feb. 2 (Xinhua) -- China's first shared education satellite Nike Air Max 90 White Shoes , Young Pioneer 1, carried by the Long March-2D rocket, was launched into space from Jiuquan Satellite Launch Center Friday afternoon.


The 3-kg CubeSat (100 * 100 * 340mm), Young Pioneer 1, enters an orbit of 502 km above the Earth. The rocket also carried Zhangheng 1 Nike Air Max 90 Off White Shoes , an electromagnetic satellite to study earthquake data, and five other miniaturized satellites.


Young Pioneer 1 was manufactured and tested by Commsat, a Beijing-based private satellite company funded by the Xi'an Institute of Optics and Precision Mechanics under the Chinese Academy of Sciences (CAS).


It will perform wireless storage and transmission of radio waves at UV frequency, space imaging and the verification of user links to the Internet of Things, said Xie Tao Air Max 90 White Leather Shoes , founder and CEO of Commsat.


After in-orbit tests, Young Pioneer 1 will share its data resources with primary and secondary schools and other education institutions equipped with sub-stations in China. It will provide students with experiences like wireless communication and space photography, Xie said.

GAZARAMALLAHJERUSALEM, Nov. 6 (Xinhua) -- Two Palestinians were killed and four Israelis were wounded on Friday in another day of violent clashes between Israel and the Palestinians in the West Bank and Gaza Strip, officials said.


In Gaza Air Max 90 Black Leather Shoes , a 23-year-old Palestinian young man was shot dead and nine wounded in clashes on Friday between dozens of young men and Israeli soldiers at the borderline area between the Gaza Strip and Israel.


Ashraf al-Qedra, spokesman for the Gaza health ministry, said that Salama Abu Jame'a, from the southern Gaza Strip town of Khan Younis, was killed and nine others were injured by Israeli troops' gunfire.


Witnesses said that dozens of young men rushed to the borderline area between the Gaza Strip and Israel and clash with the Israeli soldiers. The soldiers fired back tear gas Air Max 90 Leather Shoes , rubber bullets and live ammunition.


Al-Qedra said that 18 Palestinian young men were killed and more than 300 wounded since the beginning of the wave of tension between Israel and the Palestinians that started in Oct. 1 allover the Palestinian territories.


In the West Bank, the Palestinian health ministry said that a 72-year-old woman was shot dead after she drove a car that ran over several Israeli soldiers near the southern West Bank city of Hebron, where one soldier was injured.


The health ministry said in an official emailed statement that Tharwat Sha'rawi, 72, died after she was critically wounded when Israeli soldiers opened fire at her while she was driving her car near Hebron.


A wave of tension and violent confrontations broke out in early October allover the Palestinian territories between Israel and the Palestinians. The wave of tension had so far killed 78 Palestinians and 11 Israelis and wounded more than 2 Air Max 90 Black Shoes ,000 in both sides.


The Palestinians call the wave of violence in the Palestinian territories ""the Intifada of al-Quds"" or the Uprising against Israel following the Israeli measures of dividing al-Aqsa Mosque compound in east Jerusalem in late September, while Israel calls it a wave of terrorism.


Similar clashes had also broken out in the West Bank, mainly near Ramallah and in the southern city of Hebron. The Palestinian health ministry said that more than t.
